Abstract: An induction heating and wireless power transferring device that includes: a first working coil and a second working coil that are coupled in parallel; a rectification unit configured to rectify alternating current (AC) power to direct current (DC) power; a first inverter unit configured to convert the DC power into resonant current, and apply the converted resonant current to the first working coil or the second working coil; a first switch coupled to the first working coil and configured to turn on or off the first working coil; a second switch coupled to the second working coil and configured to turn on or off the second working coil; and a control unit configured to control the first inverter unit, the first switch, or the second switch to detect whether a target object is located on the first working coil or the second working coil.
